I have just bought an O8 sti a few weeks back and pretty pleased with it. except for the transmission. during the test drive and owning the car i have noticed that while downshifting and the clutch is not engaged the transmission makes a slight grinding. like the engine is trying catch up in the lamest of words. i thought it was the transaxle...maybe i am wrong but probably am. it has 72k on it, and its in very good shape. just confused on what that noise may be.
